Giuliani, Pataki, and Schwarzenegger are not running for President. They didn't plan photo-ops receiving Communion either. Certain people in the Church DID come down on Arlen Spector(r), and on Rick Santorum(r) for supporting him. Before he died, Cardinal O'Connor locked horns with Giuliani all the time. It just happens that one party has support of this intrinsic evil as part of their platform, while the other party has resistance to it as part of theirs. But even so, the Church doesn't deal with the "party". The policy is to deal with the individual views of each politician...
"Giuliani, Pataki, and Schwarzenegger are not running for President. "
So? How does that lessen their public support for abortion?
Note: I hate sKerry the FlipFlopper. I in no way support him. But precedent is being set here that may have negative effects years from now regarding issues other than abortion.
I mean, replace "Abortion" with "War on Terror" and you'd have to deny our President (if he was Catholic) Communion, according to the Vatican. If there's ever a "Vatican III" and they religiously outlaw war, will you support their denial of Communion to a politician who feels it's important to defend their country?
